Curated OER
World Wide Winds
High schoolers recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.

Finding the Ages of Rocks and Fossils
Young scholars practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.
Curated OER
Chemical Calculations and Chemical Formulas
In this stoichiometry activity, students calculate molar masses, empirical and molecular formulas to solve 105 problems and short answer questions.
Curated OER
Excavating the Past
Students discover how palaeontologists conduct a dig for fossils and how they interpret the age of the fossils. In small groups, they prepare a "dig site" consisting of bones, rocks and soil layered in a cardboard box. They switch boxes...
Curated OER
Polishing the Petoskey
Students select a stone and polish it. Throughout the process they demonstrate an understanding of rocks and fossil formation.
Curated OER
Reactor Incident
Students are introduced to Chernobyl incident and the resulting environmental health impacts they watch a PowerPoint presentation, read articles and discuss what they have gained from these sources.
Curated OER
How does Nuclear Fission differ from Nuclear Fusion?
Students examine concepts of nuclear chemistry. They compare and contrast the topics of nuclear fission and nuclear fision. They predict the outcome of reactions based on the types of emissions and reactants.
